Speccetion of Letters Patent.

Patented Nov. 1,3, 1906.

Application tiled May 26,1906. Serial No. 318,856.

To all whom, it may concern:

Be it known that I, ARVID M. Lnvrn, a citizen of the United States, residing at Chicago, in the county of' Cook and State of Illinois, have invented certain new and useful linprovements in Gas-Producers, of which the following is a specification.

My invention relates to gas-producers, and particularly to that type of such machines commonly vcalled suction producers, wherein a low of `as from the producer and a flow of air and air and moisture thereto is induced by the suction action oi an explosive- 'engine connected therewith in drawing iu its charge.

ln the successful and economical operation of this class of machines it is important that the flow of air and air and moisture to the producer for the purpose of aiding combustion of the fuel and enriching the gas be properly proportioned in order to prevent e too high degree ot' heat and consequent incandescence oi the fuel.

The object ot my invention is to provide ineens whereby the proportion of air an d air and moisture flowingh into the producer' will be governed by the degree ol heat ol` the ou ti'lowiug gases by 'menus ol' :i thermostat lovcated 1n the path of the outllow oi from the producer and receiving heut therefrom, said thermostat beine; connected with n valve mechanism adapted to control the admission of air and oi a' and moisture to the producer.

An enihodimei'it ol" my invention is illustinted in the :ici-.ompanying drawings, in which-- Figure l is an elevution ol' a gus-producer and engine attached. Fig. l is a sectional elevation oi' n vuporizer connectedwith the gris-conduit bending from the producer and in which is mounted u thermostnt adapted. to control the nir und nir und moisture admitted to the producer. l=`i;r. 3 is u I iss-srwl.ion 0i Fig. Z ou line A l5, Fig. Ll is u. cross-section ol' Fig. 'l on liuc l). l" 5 is a cross-sectron oi' Fig. L? ou line ii l?. Fig. 6 is e. plan View ol' the lever emmer-tions between the air and air and moisture governing valve and the oporuiive ond of the lherinostut. Fig'. 7 is a plan vien` ol' ahr. iunior ond of' the vaporizcr on an enlnrfd scalo; und Fig. S is a sectional elevation ol n Apart of the upper portion of Fig. 2, on nu enlarged sonic, showing the manner oi connecting the thermostat with the tir and nir and moisture controlling valve.

Like reference-numerals designate the same parts throughout theseveral'views.

l represents a producer, which may be of any desired forni.

2 is a vaporizer connected with the producer.

3 is e scrubber, and 4 represents an eXplosive-engine, receiving gas from the scrubber' b v means ot a pipe connection 6 represents a gas-conduit lending from the upper part oi' the producer to an inelosed chmuher 7. secured to the upper end of the vaporizer 2.

The vsporizer comprises in its preferred form a cylindrical shell portion 8,. having` l'langes .9 and 1U secured to its upper und lower ends, respectively, and l l and l2 .represent upper and bottom. plates, the plate l] beingh interposed between the lower end el' the chamber 7 and the harige 9 and the plete 12 between the flange l0 and a chamber i3, secured to the lower end of the vaperiser. The upper one iower chambers 7 and i3' coinrnunicate with each other by ieans'oi' a series oi tubes le, having their opposite ends secured in openings in the plutes und arranged concentricztllv with the longitudinal axis olv the cylindrical shell.

l5 represents n tube axinlly arranged in the cylindrical shell and surrounding an inner tube 15, lenving an intervening sgat-ey between them for the reception of a nou-conductor of heat, such as asbestos paper.

16 represents a thermostat coniprising` :i brass tube having its lower end secured, to the bottom oi the chan'rber l?) and extending* upward within the inner tube l5 and provided at its upper end 'with a egudgeon 17, secured thereto and slidably mounted in a bearingblock i-e, adjusts-bly mounted in the upper wall ift-the chamber 7. Secured to the 'upper part oi' the chamber 7 is n. head portion i9, having` a lower anriular chamber 20, lomlnunieating with the veporizer by means of u vertical conduit 21 atene side et the chamber 7 ZQ-represents a. mixing-chamber formed in the head portion l i), and communicating therewith is a pipe 23, leading'to the producer', and 24 is a cylindrical shell, secured at its opposite ends in openings in the upper end lower walls Aof the niiXing-clnunher Z22 and havingl a series of longitudinally-errunged ports opening into said chamber.

25 represents e piston-vulve mounted in the producer,

he shell 24 and having a stem 26 secured thereto, the lower end of the stem being pivotally connected with one end of a lever 27, having its opposite end pivotally connected with the wail of the chamber by means of a pin 28.v l

29 represents' a lever having one end pivotally connected with the wall of the chamber upon the op osite side of the valve-stem 26y by means o a pin 3() and comprising two arms'31 and 32, arranged upon opposite sides of the lever 27 and extending parallel therewith, and a central ear portion 33, provided with an adjustable screw-threaded pin 34, having its lower end arranged to contact with the upper end of the gudgeon 17.

is a spring-pressed plunger having its lower end pro vided with a slotted head-piece that is pivotally connected with the lever 27 and the arms 31 and 32 of the lever 29 by means-of the pin 36 and having an upper stem portion slidably mounted in an adjustable bearing-block 37, mounted in the upper wall of the chamber 2() and having a coiled springx38 surroundiugt @stem and operativel between the .lowerfentl of the bearingblock and the enlarged lower end of the plunger in a manner to yieldingly hold the screwpin 34m contact with the thermostat.

The arms 31 and 32 and the lever 27 are provided with a series of lateral openings 39, through which the pin 36 may be passed for the purpose of adjusting the movement or' the valve as controlled by the thermostat. Vhen the pin 36 is removed from its connection with the plunger 35 and placed in either of the openings 39 for the purpose of adjusting the throw of the valve, a shorter pin is used to connect the plunger with the lever 27.

A pipe 40 connects the chamber 13 with the scrubber 3, and `41 represents the usual relief-pipe connected therewith. Water is supplied to' the vaporizer by means of a pipe 42, connected with a source of supply, and 43 represents a drip or overliou. pipe leading from the vaporizer, and 44 is an air-supply pipe communicating with the vaporizer. 45 is a hand-hole through the shell ot' the vaporizer at its lower end for the convenience 'of the operator in cleaning the chamber, and 46 represents a similar opening in the wall of chamber 13. '47 represents a valve control-- ling the supply of air and air and moisture to and 48 is avalve controlling the supply of water to the vaporizer.

VVhen'tlie engine'is ruiming steadily with a uniform. load, little or no change is required in the volume or proportions of the mixture of air and moisture, as the gas drawn from the producer is practically uniform in temperature; but if the load upon the engine increases a larger volume of gas is required, and consequently a greater draft is created sitiveness of in the producer, increasing the degree of incandescence of the burning coal, and conse- 1 @sacas quentl the degree of heat of the gas delivered from t e producer and flowing through the chamber 7 andthe tubes 14 and 15 into chamber 13 and thence to the scrubber.

The hot gases flowing through the tubes 14 raise the temperature of the water in the vaporizer, and steam is mixed with the air drawn therein through the air-pipe-connection. The air and moisture are' drawn through the conduit 21 and through the openf ings in the shell 24 o the mixing-chamber 22, where it becomes mixed withair drawn into the chamber through the upper end of the shell, and the pipe 23 conducts the mixture to the producer. As the temperature of the gases drawn downward through 'the tube 15 is increased or diminished the thermostat 16 expands or contracts in length, and through its connection with the valve 25 raises or .lowers it in the shell 24 in a manner to regulate the supply of air or of air and moisture drawn ythrough the pipe 23, the senthe movement of the valve as controlled by the thermostat being regulatedby means of the adjustable connection between the .lever 27 and the arms 31 and 32 of the lever 29.
